Waste management strategies in mining projects will depend to a large extent on the characteristics of the operational process, the type of ore and prevailing socio-environmental conditions, amongst other issues. The expenditures required by the management scheme and the implementation of remediation programs will be determined by the extent that the above issues were considered in the planning phase of the project. Several works have been published in the literature concerning the analysis of waste management programs and environmental impacts associated with uranium projects around the world. However, the vast majority do not report a comprehensive assessment integrating the various relationships among operational process, environmental impact, remediation strategy and costs. This study, divided into two papers, presents a detailed critical analysis of the waste management strategies adopted in two uranium production centres in Brazil, i.e., the Poços de Caldas Project (Part I) and the Caetité Project (Part II). The operational processes are described and the environmental impacts of the generated wastes as well as the adopted management strategies and costs are examined. Also, in Part II, a comparison between both production centres is made emphasizing the impacts of environmental and social-economical issues on the overall assessment.  相似文献

Recent “green” planning initiatives envision food production, including urban agriculture and livestock production, as desirable elements of sustainable cities. We use an integrated urban political ecology and human–plant geographies framework to explore how foraging for “wild” foods in cities, a subversive practice that challenges prevailing views about the roles of humans in urban green spaces, has potential to also support sustainability goals. Drawing on research from Baltimore, New York City, Philadelphia, and Seattle, we show that foraging is a vibrant and ongoing practice among diverse urban residents in the USA. At the same time, as reflected in regulations, planning practices, and attitudes of conservation practitioners, it is conceptualised as out of place in urban landscapes and an activity to be discouraged. We discuss how paying attention to urban foraging spaces and practices can strengthen green space planning and summarise opportunities for and challenges associated with including foragers and their concerns.  相似文献

Urban public spaces are important areas for leisure, recreation and physical activity and therefore contribute to the quality of life in cities. In particular, for adolescents they provide important spaces to meet with their peers, away from parental or school control. In many cities worldwide, public spaces have undergone severe developmental processes, and often a withdrawal from public space is noted. With regard to the opportunities those spaces provide for adolescents, it is necessary to investigate their current meaning for adolescents in a leisure context. In this article, qualitative research methods were used to investigate factors affecting adolescents’ use of public spaces in Vienna, Austria. In total 45 adolescents were interviewed. Results show that public open spaces are not regarded as important leisure spaces, and data reveal a strong retreat to private areas for leisure purposes. Perceived insecurities and fears support these processes and often result in avoidance of public spaces but also the wish for more control by authorities.  相似文献

The aim of this paper is to describe a method for evaluating the vulnerability of drinking water systems to contamination, in particular in rural regions used intensively for agriculture. To do so, various indicators were developed to represent the source to tap multi-barrier approach for drinking water safety. These indicators correspond to four barriers: source susceptibility to contamination; water treatment efficiency; distribution system management; and, overall management of water quality. The indicators were classified, regrouped and weighted within a model based on a multi-criteria analysis. The method was developed and applied to 39 municipal water systems of rural Quebec, Canada. The model obtained can be used for planning purposes to prioritise water systems requiring improvements.  相似文献

Sustainable development and solutions to existing environmental problems depend heavily on information and its translation into usable knowledge. Increasingly, affected communities are being drawn into environmental decision‐making, both in the development of strategy (plans) and in the delivery of plans through management and operations. Variants of the ‘natural capital’ theme are popular amongst those who see an effective dialogue between the sciences of ecology and economics as the most promising interdisciplinary context for environmental decision making by empowered communities. A decision‐making framework is vital in practical, community‐based schemes (wider than ‘stakeholder platforms’) which have become popular for promoting ‘best practice’ in managing river basin units. The EU Water Framework Directive renders use of interdisciplinary techniques within a participatory framework a statutory requirement. A final practical need for communities and professionals involved with such schemes is the creation of a system of adaptive (rather than reactive) management, supported by ongoing research and monitoring to detect, and adjust to, ever‐changing physical and social contexts for both strategies and operations.

This paper describes the authors' experience in applying the ‘Environmental Capital’ (also known as ‘Quality of Life Capital’ (QoLC)) approach to information management in two headwater catchments in northern England: the Wharfe and the Coquet. In the case of the Upper Wharfedale Best Practice Project (UWBPP) the components of basic environmental survey, consultation, strategy formulation and the use of the strategy are illustrated to guide immediate and longer‐term actions. In contrast, the Coquet application of the technique, whilst socially more pervasive, was less successful for a number of reasons: geographical, institutional, project and participatory.

As a proposed development of the methodology based on the authors' experiences, extending public participation through monitoring activity, together with formal application of environmental economics to the perceived elements of ‘natural’ and ‘human’ capital in the two catchments would appear desirable. Conclusions are also drawn regarding the demands of the EU Water Framework Directive for ecological, economic and participatory approaches to river basin planning and management.  相似文献

Understanding the magnitude and location of soil phosphorus (P) accumulation in watersheds is a critical step toward managing runoff of this pollutant to aquatic ecosystems. Here, I examine the usefulness of urban–rural gradients, an emerging experimental design in urban ecology, for predicting extractable soil P concentrations across a rapidly urbanizing agricultural watershed in southern Wisconsin. I compare several measures of an urban–rural gradient to predictors of soil P such as soil type, slope, topography, land use, land cover, and fertilizer and manure use. Most of the factors that were expected to drive differences in soil P concentrations were found to be poor predictors of Bray-1 (extractable) soil P, which ranged from 4 to 660 ppm; while there were several significant relationships, most explained only a small proportion of the variation. A multiple linear regression model captured approximately 37% of the variation in the data using the urban–rural gradient, topography, land use, land cover, manure use, and soil type as predictors. There was a significant relationship between Bray-1 P concentration and each of the urban–rural gradients, but these relationships explained only between 2.6% and 3.3% of the variation in P concentrations. Extractable P concentration in soils, unlike some other ecosystem properties, is not well predicted by urban–rural gradients.  相似文献

In the context of the desire to steer urban transformation towards sustainability transition, the development of proposals for alternative futures assists policy-makers and practitioners in focusing on impact by organising the various drivers, particularly spatial ones that cause an interactive urban system to transit. This paper presents the methodology that has been developed by the Chair for Urban Development, Munich University of Technology (TUM) as it was working within an inter-disciplinary research team on a project commissioned by the municipality of Nuremberg. The objective of this project was to develop ideas for regenerating the formerly industrial area of Nuremberg West (NW) under the guiding theme of sustainable urban development. This methodology focuses on the development of proposals of positive and possible transformations of NW in the year 2050 based on the analysis of economy, housing and space at various scales and a systematic assessment of trends. These alternative futures became framing and guiding narratives to internalise and anchor the debate in-between the various disciplines involved in this project.  相似文献

Current research on household food waste has not considered the impact of the inter-class power dynamics between employers and domestic helpers on food waste management and generation in the Global South. This article focuses on the issue of food justice and will demonstrate that it is important to reconsider household food practices within the framework of unequal power dynamics in household units – especially between employers and their domestic helpers. Informed by food waste regime conceptual framework, this paper will examine the complex food provisioning practices of Indonesian households. The research draws on 21 in-depth interviews with households of varying incomes, multiple site visits, participant observation and going along on grocery trips to better understand the power dynamics and practices that result in, or prevent the generation of household food waste. In addition, 12 key informant interviews with government officials, traditional food vendors, supermarket managers, and a waste collector was also conducted. In an Indonesian context, understanding the interclass dynamics of the household, namely, who gets to define what is “food” and what is “waste” is key to understanding the broader phenomenon of food waste in order to promote solutions to food waste prevention and food insecurity that is socially and environmentally just.  相似文献

Water planning processes in Australia have struggled to account for Indigenous interests and rights in water, including the use of Indigenous knowledge in water management. In exploring the role of Indigenous knowledge in government-led water planning processes, how might tensions between Western scientific and Indigenous knowledges be lessened? Drawing on two case studies from northern Australia we examine how Indigenous knowledge is represented and managed as a different social knowledge to that of Western science in a management context where legal and planning conventions assume priority. The role of Indigenous (social) knowledges in developing options and strategies for sustainable water management is contingent upon the participation of Indigenous people in water planning. We suggest that water planning processes must contain the possibility of an explicit approach to mutual recognition and consequent translation of the conceptual and pragmatic bases of water management and planning in both Western scientific and Indigenous domains.  相似文献

Child-Friendly Cities were conceived as a means to integrate children's rights into city decision-making and governance. Participatory research about child-friendly cities consistently finds overarching themes across ages and regions: children desire access to services, nature, and play; freedom from physical danger; and opportunities for inclusion within the city. This article explores a two-year visioning and participatory design process that engaged approximately 225 young people, aged 4–16, in the planning and design of a prominent public space in the City of Boulder. While participatory research with children has received much attention in the academic literature, much less attention has been given to what can be achieved through sustained integration of children into municipal planning processes, particularly in the USA. This paper thus moves children's participation beyond rhetoric and into the challenging reality of planning a city with children as a valued constituent.  相似文献

This paper examines the complex social reality of mixed ethnic residential areas, as reflected in drawn perceived neighbourhoods of Jews and Arabs living in homogenous and mixed neighbourhoods in Jaffa, Tel Aviv. Through in-depth interviews conducted among 89 Jaffa's residents, it illustrates how different perceptions about the residential area and its residents (including attitudes, emotions, feeling of fear/safety, collective identity and tolerant relations) are reflected in the form, size and consensus area of residents' perceived neighbourhoods. The study finds a clear association between tolerant attitudes and the size and consensus area of the perceived neighbourhoods. Arabs perceive their neighbourhood as significantly larger than Jews do and are characterised by a larger consensus area. These findings are explained by the Arab's strong social cohesion, common national identity, rootedness in Jaffa, as well as by tolerant attitudes towards Jaffa's Jewish population. The study demonstrates the interrelation between the spatial, social and perceptual dimensions associated with the mixed residential area, and illustrates how these dimensions are reflected in drawn perceived neighbourhoods.  相似文献

Given the likelihood that a post-Kyoto climate change agreement will include provisions for trading greenhouse gas (GHG) emission rights (carbon credits), it is timely and important to look more closely into the merits (or otherwise) of emissions trading systems (ETS), in particular with regard to the issue of the allocation and distribution of entitlements. Thus far, ETSs and other tradable permit systems have allocated entitlements to those historically responsible for emissions or the exploitation of resources (the “grandfathering” principle). There are, however, strong reasons for challenging this practice, and for advocating the allocation of entitlements to all people, in line with the per capita distribution principle. This article argues that GHG emission rights, if they are to be granted, should be distributed on a globally determined equal per capita basis, but collectively managed by community bodies (Community Carbon Trusts) on an “individuals-in-community” basis, instead of being granted or sold by governments to (big) emitters. The approach advocated here is not only ethically more justified, but also strengthens the capacity of communities to deal with climate change and to advance sustainability. It offers an example of how a significant environmental challenge can be met in a more positive way than by the prevailing approaches based on narrow, mainly economic, considerations.  相似文献

In Lesotho, climate change adaptation funding is being managed and distributed by the same mechanisms which have traditionally operationalised humanitarian aid and international development assistance in the country. Lessons from the HIV/AIDS disaster, along with insights into the value of participatory approaches foregrounding the expertise of indigenous communities, must be heeded in order to ensure that those most affected by climate change have a say in how adaptation is carried out. This paper proposes that indigenous people have developed and actively maintained resilience strategies, encoded in social practices and farming techniques, designed out of long experience with climatic variability. Through case studies, indigenous resilience strategies are explored, with emphasis on the anarchistic, improvisational nature of traditional ecological knowledge. Future directions for policy-makers and practitioners dealing with climate change adaptation are suggested, namely the need to foreground indigenous knowledge and the experiences of frontlines experts in key policy arenas.  相似文献

Elderly women of a particular socioecological system are considered to be “living encyclopedias” in biocultural knowledge systems. These women play a pivotal role in retaining and passing on biodiversity-related traditional knowledge to the next generations. Unfortunately the fast changing sociocultural values and the impact of modernity have rendered their knowledge somewhat less valuable and they are being treated as “cultural refugia.” Our study on the importance of these women in the conservation of indigenous biodiversity was conducted in 14 randomly selected villages dominated by the Adi tribe of East Siang District, Arunachal Pradesh (northeast India). Data were collected from 531 women (381 elderly and 150 young to middle aged) during 2003–2008 using conventional social science methods and participatory rural appraisal. One innovative method, namely “recipe contest,” was devised to mobilize Adi women of each village in order to energies them and explore their knowledge relating to traditional foods, ethnomedicines, and conservation of indigenous biodiversity. Results indicated that 55 plant species are being used by elderly Adi women in their food systems, while 34 plant species are integral parts of ethnomedicinal practices. These women identified different plant species found under multistory canopies of community forests. Elderly women were particularly skilled in preparing traditional foods including beverages and held significantly greater knowledge of indigenous plants than younger women. Lifelong experiences and cultural diversity were found to influence the significance of biodiversity use and conservation. The conservation of biodiversity occurs in three different habitats: jhum lands (shifting cultivation), Morang forest (community managed forests), and home gardens. The knowledge and practice of elderly women about habitats and multistory vegetations, regenerative techniques, selective harvesting, and cultivation practices contribute significantly to food and livelihood security while sustaining an array of threatened plant species. Basically, knowledge of elderly women on using biodiversity in food and medicinal systems was found in three categories namely: “individual,” “community,” and “refined.” We identified a need to develop holistic policies to recognize and integrate knowledge and practices of elderly women with local level of planning on sustainable conservation of biodiversity as well as community-based adaptations.  相似文献

Advancement of modern agricultural biotechnology has brought various potential benefits to humankind, but at the same time ethical concerns regarding some applications such as genetically modified foods (GMF) have been raised among the public. Several questions are being posed; should they utilize such applications to improve quality of their life, or should they refrain in order to save themselves from any associated risk? What are the ethical principles that can be applied to assess these applications? By using GMF as a case study, this paper discusses possible answers to these questions from Islamic perspective. Such answers are based on the understanding of the Islamic concept of maslahah (benefit) and mafsadah (harm) as well as the Islamic principles of priority. There is no specific GMF that has been declared as unlawful by Muslim scholars thus far. Nevertheless, they generally state that any GMF that contains unlawful substance is prohibited in Islam. Such statement can be understood since Islam puts highest priority to preserve shari’ah (Islamic law) which prescribes the lawful and unlawful things in human life. Priorities have also been given to preserve human health and environment therefore any GMF that may inflict harm on both entities is also considered as unlawful.  相似文献

In the last fifty years, many mountain watersheds in temperate countries have known a progressive change from self-standing agro-silvo-pastoral systems to leisure dominated areas characterized by a concentration of tourist accommodations, leading to a drinking water peak during the winter tourist season, when the water level is lowest in rivers and sources. The concentration of water uses increases the pressure on “aquatic habitats” and competition between uses themselves. Consequently, a new concept was developed following the international conferences in Dublin (International Conference on Water and the Environment – ICWE) and Rio de Janeiro (UN Conference on Environment and Development), both in 1992, and was broadly acknowledged through international and European policies. It is the concept of Integrated Water Resource Management (IWRM). It meets the requirements of different uses of water and aquatic zones whilst preserving the natural functions of such areas and ensuring a satisfactory economic and social development. This paper seeks to evaluate a local water resources management system in order to implement it using IWRM in mountain watersheds. The assessment method is based on the systemic approach to take into account all components influencing a water resources management system at the watershed scale. A geographic information system was built to look into interactions between water resources, land uses, and water uses. This paper deals specifically with a spatial comparison between hydrologically sensitive areas and land uses. The method is applied to a French Alps watershed: the Giffre watershed (a tributary of the Arve in Haute-Savoie). The results emphasize both the needs and the gaps in implementing IWRM in vulnerable mountain regions.  相似文献

Rural sociologists and geographers have conceptualised different rural development trajectories including “the agri-industrial model”, “the post-productivist model” and “the rural development model”. Alternative food networks (AFNs) are increasingly recognised as a “forerunner” and a critical component of the emerging “rural development model” in the West. Meanwhile, Marsden and Franklin [2013. Replacing neoliberalism: theoretical implications of the rise of local food movements. Local Environment, 18 (5), 636–641] pointed out that there is a “local trap” in the current conceptualisation of AFNs that overemphasises their local embeddedness and heterogeneity. This “local trap” marginalises AFNs and, therefore, hinders their potential for transforming the industrialised conventional food system. The convergence and scaling-up of fragmented AFNs have been recognised as important ways to address this marginalisation issue and thus have attracted considerable attention. However, current studies of the convergence of AFNs focus mainly on the role of food-centred organisations without recognising the role of the emerging “rural development” initiatives in the convergence of AFNs. Based on in-depth interviews with key stakeholders and analysis of secondary data, this paper uses the New Rural Reconstruction Movement (NRRM), an emerging alternative rural development movement in China, as an example to illustrate how the NRRM opens up a novel space for the convergence of AFNs. We argue that the interrelationship between AFNs and rural development is indeed reciprocal. The NRRM, following the “rural development” trajectory, functions as a hub for the convergence and scaling-up of various alternative food initiatives. Strategies for achieving convergence include constructing a “common ground” for these initiatives, establishing national alliances and organisations, sharing knowledge and exchanging personnel among them.  相似文献
